Studies• Clinical studies have reported seed extracts to inhibit red blood cell sickling and potential benefit for people with sickle cell anemia.
• Antiplasmodial constituents of Cajanus cajan: Study shows compounds from roots and leaves of CC showed moderately high in vitro activity against Plasmodium falcifarum strain.
• Hypocholesterolemic Effect: Study on the stilbenes containing extract-fraction of CC showed a hypocholesterolemic effect possibly through enhancement of hepatic LDL-receptor and cholesterol 7-alpha-hydroxylase expression levels and bile acid synthesis.
• Evaluation of traditional medicine: effects of Cajanus cajan L. and of Cassia fistula L. on carbohydrate metabolism in mice: Contradicting its traditional use for diabetes, CC did not have a hypo effect on sugar, aand at higher doses produced a hyperglycemic effect.• Antimicrobial: Antimicrobial effect of leaf extracts of pigeon pea (Cajanus cajan (L.) millsp.) on some human pathogens : Study shows the plants extract to be inhibitory to some bacterial pathogens.
• Antimicrobial / Antifungal: Nigerian study on the antimicrobial effects of the ethanol and aqueous extracts of locally available plants, including C cajan, showerd inhibition against S aureus, P aeruginosa, E coli and C albicans. The extracts of C cajam produced wider zones of inhibition against C albicans.• Hyperglycemic Effect: Study of the aqueous extract of C cajan leaves showed a hyperglycemic effect, suggesting a usefulness incontrolling hypoglycemia that may be due to excess of insulin or other hypoglycemic drugs.• Hepatoprotective: Study of the methanol-aqueous fraction of C cajan leaf extract showed it could prevent the chronically treated alcohol induced rat liver damage and presents a promise as a non-toxic herb for therapeutic use in alcohol-induced liver dysfunction.

Studies
• Antimicrobial activity of Caesalpinia pulcherrima, Euphorbia hirta and Asystasia gangeticum: Studies on the ethanolic extracts of the dry fruits of C. pulcherrima showed a broad spectrum of antimicrobial activity against E. coli (enteropathogen), Proteus vulgaris, Pseudomonas aeruginosa and Staphylococcus aureus.
• In vitro antiviral activities of Caesalpinia pulcherrima and its related flavonoids: A study showed a potential for use in the treatment of infection caused by two viruses: herpesviruses and adenoviruses.
• Anti-inflammatory activities of flavonoids isolated from Caesalpinia pulcherrima: The study supports the use of Caesalpinia pulcherrima for the treatment of inflammtory conditions in traditional medicine.
• Furanoid Diterpenes / Antibacterial / Antifungal : Study isolated four new cassane-type furanoditerpenoids from the leaves of CP. Antimicrobial testing showed activity against bacteria (S aureus, E coli, P aeruginosa and B subtilis) and fungia ( C albicans and T mentagrophytes).
• Nutrient studies of CP Seeds: Study suggests C pulcherrima could be a good source of low cost plant protein, a good source of iron and calcium; the whole seeds more nutrient-rich than the seed nuts.
• Flavonoids / Antiinflammatory: Study isolated five flavonoids from CP which significantly and dose-dependently inhibited inflammatory mediators, NO, cytokines (TNF and IL-12).
• Antifungal: Study of methanol extract of 9 Indian medicinal plants showed C pulcherrima with good antifungal activity against C albicans.

There is a wide range of benefits of ginger such as nausea, digestive problems, circulation and arthritis. Nausea caused during pregnancy or by travelling is one of the benefits of ginger root. Ginger is also known to have the ability to calm an upset stomach and to promote the flow of bile. Stomach cramps can be eased and circulation can also be improved. Ginger supports a healthy cardiovascular system by making platelets less sticky which in turn reduces circulatory problems.

Ginger oil used for massage can help relieve painful arthritis due to its anti-inflammatory properties. Ginger is often included in many herbal decongestants and can help to minimise the symptoms of respiratory conditions, colds and allergies.

With all the benefits of ginger and continuing research, the ginger root is fast becoming a very popular medicinal herb.
